- Doppel raised $70M in Series C funding at $600M+ valuation to combat AI-powered social engineering attacks, which have surged 300% annually. - The AI platform uses machine learning to detect anomalies like deepfake voice modulation and AI-generated phishing emails in real-time. - While Doppel expands partnerships, VeriSign and C3.ai face scrutiny over stock sales and declining revenues amid AI adoption risks. - Doppel CEO Alex Johnson warns that AI security tools risk becoming vulnerabilities themselves

Doppel, a cybersecurity company focused on AI-powered threat detection, has raised $70 million in Series C funding, pushing its valuation above $600 million. The investment round, led by unnamed backers, highlights increasing worries about AI-driven social engineering threats,

which have risen by 300% over the last year

, as reported by industry analysts. This capital will help Doppel further advance its AI platform,

built to detect and counter advanced phishing and deepfake attacks

that take advantage of generative AI technologies.

The firm’s system uses machine learning to examine communication behaviors, spotting irregularities such as altered voices in calls or AI-created content in emails. Doppel’s products are

already in use by leading banks

and Fortune 500 firms,

which experience an average of 12,000 cyberattacks each month

. Doppel intends to broaden its services to offer real-time threat mitigation and to collaborate with cloud providers, integrating its solutions into business operations.

By comparison,

VeriSign

, Inc. (VRSN) has opted for a more defensive strategy,

unveiling a $1.11 billion share repurchase initiative

while keeping its dividend yield at 1.2%.

This follows insider sales totaling $12.99 million

over the past three months, with company leaders cutting their stakes by as much as 8.04%. Despite these moves,

VeriSign’s market value has stayed steady

, thanks to its critical role in internet infrastructure and domain registration services.

The semiconductor industry also delivered mixed signals.

Taiwan Semiconductor Manufacturing Company (TSMC)

increased its quarterly dividend to $0.9678 per share, showing confidence in its 26.97% payout rate. On the other hand,

institutional investors such as Westwood Holdings Group Inc.

have trimmed their positions in TSMC, reflecting caution amid ongoing global supply chain challenges.

C3.ai Inc. (AI), which develops AI-based enterprise applications,

encountered volatility as its chairman, Thomas Siebel

sold $8.3 million in shares through a pre-set trading arrangement.

Siebel also registered to sell another 724,318 shares

via a Form 144 submission,

prompting concerns about the company’s future prospects

in light of a 20% year-over-year drop in revenue.

The differing outcomes for these companies illustrate the double-edged sword of AI integration. While Doppel and Citigroup are pouring resources into AI to boost security and productivity, firms like C3.ai and VeriSign are contending with the pitfalls of heavy dependence on emerging technologies. As Doppel CEO Alex Johnson remarked, "The battle against AI-enabled threats is just starting. The next challenge is making sure our defensive tools don’t become weaknesses themselves."
